Abstract

The invention provides a long section dyed colored yarn which is produced by blending two or more than two types of fibers in different colors. At least one type of the fibers is subjected to section dyeing by a section dyeing unit using two or more than two types of dye solution different in color, and spacing of color sections is 10-100cm. A production method of the yarn includes processes of fiber material: firstly, reeling fiber material to obtain hank yarns; secondly, subjecting the hank yarns to section dyeing on the section dyeing unit according to the spacing of the color sections of 10-100cm; thirdly, performing fixation; and fourthly, blending the two or more than two types of fibers different in color into yarns, wherein at least one type of the fibers is treated by the section dyeing process carried out in the step 2. Section colors of the colored yarn are variable and regular out of irregularity, and are stereoscopic in plane with rich layering. The spacing of the color sections reaches 10-100cm, the long section dyed colored yarn can be spun on a common knitting machine into the yarn with the same style as that spun by a line adjusting machine, cost is reduced, and production efficiency is improved.

Description

technical field [0001] The invention belongs to the field of textiles, and in particular relates to a long-segment segment-dyed colorful yarn and a production method thereof. Background technique [0002] Color spun yarn is generally a yarn made by mixing two or more fibers of different colors. The fabric made of color spun yarn has a hazy and natural color, which is very popular among consumers. However, in the existing color spinning system for a long time, no matter it is two-color or multi-color, each yarn has a common rule, and there is only one uniform color from the beginning to the end. No matter how the woven fabric changes, it is inevitable. There are regular colors that are uniform and regular, and the style is monotonous and uninspiring. After long-term use, consumers are prone to visual fatigue. How to break through its regular style has become a problem for the color spinning industry to think about and explore. Contents of the invention [0003] The presen...
